| Subject: CVE-2024-41093: drm/amdgpu: avoid using null object of framebuffer |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/amdgpu: avoid using null object of framebuffer |
| |
| Instead of using state->fb->obj[0] directly, get object from framebuffer |
| by calling drm_gem_fb_get_obj() and return error code when object is |
| null to avoid using null object of framebuffer. |
| |
| The Linux kernel CVE team has assigned CVE-2024-41093 to this issue. |
| |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
